Gill began work on Perpetua in 1925 at the request of Stanley Morison, typographical advisor to Monotype.[2][3] Morison sought Gill's talent to design a new typeface for the foundry. By 1929, Perpetua Roman was issued as Monotype Series 239.[4]

Perpetua was set in a limited edition of a new translation by Walter H. Shewring of The Passion of Perpetua and Felicity, giving birth to the name of the typeface and its original companion italic. The book was printed in 1929. The same type and illustrations (also done by Gill) for that book subsequently appeared in the Fleuron (number 7) which was edited by Stanley Morison and printed in 1930. Also set in Perpetua and published in 1929 was Gill's Art Nonsense and Other Essays.
The process of Perpetua's development was somewhat convoluted.[5] Gill designed two companion italic faces for Perpetua. The first, a typeface called Felicity, was a sloped roman, in which the regular style is slanted without the different letterforms of italic type. This unusual design decision was primarily due to Morison's opinion that a sloped roman form was preferable to that of cursive italics for use in book text. However, Felicity met with great criticism from Monotype management, who went so far as to declare it "worthless."[6] Perpetua's release was thus halted until Gill designed a second italic, called Perpetua Italic, which Monotype subsequently released alongside Perpetua Roman.[4] Telltale distinctions of the unused Felicity include the absence of a serif at the baseline of the lowercase d and a straight tail on the lowercase y.[4] Overall, Felicity is less sloped than Perpetua Italic.

Morison appears to have had some tension with the Monotype production team on the project, one of the British Monotype branch's first truly original designs, going so far as to commission French punchcutter Charles Malin to cut a version as an experiment without the involvement of Monotype's regular machining team at Salfords.[7][2] Mosley suggests that a rubbing of a 1655 engraving at Rye may have been an influence on the design. A slightly condensed italic alphabet Gill had drawn for Everard Meynell of the Westminster Press was considered as a basis for its italic also at one point.
While working on the project Morison engaged Gill also to begin work on a sans-serif design, which became Gill Sans.[8][9] Morison also suggested that the Times switch to a modified version of Perpetua for when asked for ideas about its redesign.[10] In the end Monotype created a new font, Times New Roman, for that project instead, but the Times did use Perpetua Titling for some sections in the metal type period.[11]
